This conference paper uses COMSOL Multiphysics simulations to evaluate thermal and SAR-based exposure limits for modeled human skin exposed to terahertz radiation (0.1–5 THz). The authors report negligible temperature increases at power densities consistent with keeping SAR below 1.6 W/kg, but note that higher power densities can yield minimal heating while producing SAR values above recognized safety thresholds. They conclude that existing sub-THz standards are not directly transferable to the full THz band and call for updated guidelines, especially for prolonged exposure.

This blinded, two-year study examined whether RF-EMF exposure at 2.4 and 5.8 GHz affects pollinator visitation to Salvia and Lavandula. The authors report no significant effect on honey bee visitation rates. They report a significant reduction in bumble bee visits per observation period under RF-EMF exposure, which they frame as a potential risk warranting further long-term research.

This review describes public concerns and scientific reports of non-thermal biological effects from low-intensity ELF and RF exposures. It lists multiple health endpoints reported to be associated with ELF and/or RF and highlights the BioInitiative Report’s conclusion that a reasonable suspicion of risk exists at environmentally relevant levels. The authors argue that existing public exposure standards should be lowered and that mobile phone SAR guidelines should be revised based on biology and long-term risk claims.
